MACHINE FOR FORMING AXLE-SKEINS.

EPZCIFICATIC-N forming part of Letters Patent No. 290,982,

dated December 25, 133C,

To all whom it may colwern:

, Be it known that 1, ANDREW O. EMMIOK, of Columbus, in the county ofFranklin and State of 1 Ohio, have invented a new and Improved Machinefor Forming AxleSkeins, of which the following is a full, clear, andexact description.

The object of the invention is to improve machines for'makingaxleslreins, as hereinafter described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of my improved axle-skein-forming machine.Fig. 2 is a sectional elevation on the line 00 x of Fig. 1. Fig.3 is asection of the taper-bending die and formingniandrel on the line 3 y ofFig.

2 and Fig. 4 a transverse section of the taper-bending die and former atz 2, where that part of the skcin is formed that extends in side of thecollar for the inner end of the wheel-hub.

I provide a taper-bed die, a, that is half round for the most of itslength, but from a point near the larger end the form changes from thehalf-round to the nearly-square form represented in Fig. 4, for shapingthe part of the skein that extends inside of the collar to correspondwith the form of that part of the wood axle to which it applies, toavoid dressing off the corners of the axle,which weakens it, and I mountsaid die a on a table, 0, that is fitted to rise and fall in the ways 0of the bed-frame d with a cam, e, on the main shaft f to raise saidtable. The fall is caused by gravity.

Over the die (1,1 arrange a taper-forming mandrel, g, which is suspendedfrom the crossbar h, so that when the die a is. raised up by cam e,witha skein-plate, t, placed on the top of it, said plate will be bent upinto a taper U shape. The cam 0 has a circular section,

5 j, of the face that is to hold die a for a suitable length of time,while the side benders, 7c and Z, move forward and bend the upper edgesof the plate over the top of the mandrel, and lap one edge over theother suitably for welding, die 7.: moving first and die 1 next.

bending dies is These Z are arranged in suitable guidcways, d, on thetopof the bed frame, and connected by studs or rollers m with the cams n onshaft f, said cams being. suitably adjusted on the shaft to work saidbenders,while the die a is held up by the cam c, and so that one willnot interfere with the other-that is, die It will withdraw in time toallow die Zto lap its side of the plate over the side bent up by die 7r.The forming-mandrelis suspended from the cross-bars h by bolts 0 andnuts 1), the bolts having collars q on the under side, over whichwashers may be placed to adjust the mandrel; but in practice I mean tosub stitute nuts for these collars as a more ready means of adjustingthe mandrel. Near the large end of the mandrel it has an arm, 3, whichis bolted at t to the head of the bolt 0, and near the small end themandrel rests in a hanger, a, which is fitted to slip off from the endof the mandrel when disconnected at c to allow the bent skeins to beslipped off the mandrel. The shaft f connects with the driving-wheel wby a clutch at a", to be connected and disconnected by a lever, y, to becon trolled by the operator for stopping the machine after each skein isformed for allowing time to remove the skein and to supply anew plate,and for starting and running the machine one revolution for bending eachskein.

The wheel 10 is geared with the driving-shaft 2 by a pinion, a, and thepower is applied to the shaft by a belt on the pulley b.

Vith this improved machine the skeins can be formed ready for weldingmuch more rapidly than they can be byhand as they are now made, alsomuch better and more uniform in shape, especially in the part extendinginside of the collar, which part may also be more definitely changedfrom the roun d to the square form which is desirable, as before stated,to avoid dressing off the corners of the wood axles to fit the skeins.

The plates are not required to be heated so much to be bent by thismachine as by hand, because of the greater power employed and theshorter time in which the work is done, so that the metalis injured lessthereby Having thus described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination, in a machine for form= ing axle-skeins, of male andfemale dies correspondingly tapered, made half round for part of theirlength, and almost rectangular near their larger ends, whereby the skeinmay be so made as to fit without dressing off and weakening the axle, asdescribed.

2. The taper-die (1, arranged on the vertically-moving table I), incombination with the taper-thinning mandrel r ,snspended over said diea, substantially as described.

3. The side binding-dies, 7c 7, iii combination with the taper-formingmandrel susl 5 \Vitncsses:
